An awe-inspiring exhibition that captures 'the ingenuity of mankind' is attracting global interest for a stunning series of images of the world's largest sun furnace and echo-free room.
The anechoic chambers at the Technical University of Denmark and the Four Solaire in the French Pyrenees (above) are two of the most advanced engineering feats of modern history.
The sci-fi looking anechoic chambers - which are designed to completely absorb sound waves - have rarely been seen as space scientists have tested state-of-the-art satellite equipment in them since first opening in 1967.
The Four Solaire delivers the world's purest power by harnessing the sun's energy and concentrating it on a single point.
The design, first built by Dr. Felix Trombe, is made up of 10,000 mirrors that can bounce sun rays at a pinpoint - sending temperatures soaring to an almighty 3,500 C.
Four Solaire in the French Pyrenees: Alistair said: These facilities are designed to be purely functional, to push the limits of heat, radio and sound waves, and they are awe inspiring in their contribution to the advancement of mankind both on our planet and in space. They are also remarkable for their visual impact. Without understanding the complexities of the functions of the facilities it is possible to marvel at the ingenuity of human beings and their ability to create such inadvertent masterpieces.
